c語言輸入數(shù)據(jù)庫
```c
#include
#include
int main(void) {
sqlite *db;
int rc;
rc = sqlite_open("test.db", &db);
if (rc) {
fprintf(stderr, "Can't open database: %s\n", sqlite_errmsg(db));
sqlite_close(db);
return ;
}
char *zErrMsg = ;
const char *sql = "CREATE TABLE COMPANY "
"(ID INT PRIMARY KEY NOT NULL,"
" NAME TEXT NOT NULL,"
" AGE INT NOT NULL,"
" ADDRESS CHAR(),"
" SALARY REAL);";
rc = sqlite_exec(db, sql, callback, , &zErrMsg);
if (rc != SQLITE_OK ) {
fprintf(stderr, "SQL error: %s\n", zErrMsg);
sqlite_free(zErrMsg);
} else {
printf("Table created successfully\n");
}
sqlite_close(db);
return ;
}
```
在這個例子中打開個SQLite數(shù)據(jù)庫,創(chuàng)建個新的表。這只是個非?;A(chǔ)的例子,實際的數(shù)據(jù)庫操作可能會更復(fù)雜。
對于高科技新材料的研發(fā)與生產(chǎn)來說,使用C語言和數(shù)據(jù)庫用來存儲和管理大量的實驗數(shù)據(jù)、材料屬性信息等。通過這種方式方便地分析和查詢數(shù)據(jù),推動我司的研發(fā)工作。
至于音樂娛樂業(yè)、專利和防腐劑等領(lǐng)域,它們從數(shù)據(jù)庫中獲益。音樂娛樂業(yè)使用數(shù)據(jù)庫來跟蹤歌曲的播放次數(shù)、用戶的喜好等信息;專利數(shù)據(jù)庫幫助研究人員查找已有的專利技術(shù),避免重復(fù)研發(fā);食品工業(yè)通過數(shù)據(jù)庫來管理和追蹤防腐劑的使用情況,確保產(chǎn)品的安全性和合規(guī)性。
